  • Transducer and system of arrangement for a panel array
    Patent number: 9214149
    Abstract: A sensor system includes a pressure sensor portion, and an accelerometer. Outputs from the sensor system are handled by a signal processing system that includes a first beamforming module for inputs from a pressure sensor, a second beamforming module for inputs from an accelerometer, and an adaptive beam interpolation module. A method for signal processing signals from both a pressure sensor and an accelerometer. An array of sensors transfers data wirelessly.
    Type: Grant

    Date of Patent: December 15, 2015
    Assignee: LOCKHEED MARTIN CORPORATION
    Inventors: Thomas J. Barnard, Thomas M. Canavan, Dane E. Reiner, Jennifer L. Pawelczyk, Casey D. Dyer, Joseph E. Nickerson, John H. Goodemote, Dennis C. Stimson, Howard R. Taylor
  • Method and apparatus for launch and retrieval of a line array attached to a towbody
    Patent number: 8985904
    Abstract: A system and method of operating a sonar system is provided. The sonar system comprises a towed body, such as a depressor body, with a towed line array attached thereto configured to be towed behind a host vessel. A line feed mechanism is operative to recover and/or deploy the towed line array from the vessel while the towed line array remains attached to the towed body.

  • Method and system for isolating and reducing grating lobe interference
    Patent number: 7936304
    Abstract: This invention relates to the use of a sufficiently-sampled auxiliary array in combination with one or more under-sampled sub-arrays. The sufficiently-sampled auxiliary array is used to create a signal-free reference (SFR) beam that contains grating lobe interference. The SFR may be used to cancel the interfering grating lobe in an under-sampled main beam by coherently eliminating or subtracting the SFR from the main beam. Exemplary aspects of the invention thus support significant under population of the full aperture and avoid the problems and limitations of previous solution, with consequent savings in sensor hardware cost and weight.
